I rebuilt the Tillotson 141B for the C5 & put it on the saw today.It started up,but ran super rich.I couldn't get any results out of adjusting the needles at all.It had no power & I had to hold the throttle wide open for it to run,no idling at all.I've rebuilt an HL carb before,so this isn't my first one.I noticed that the old inlet needle was flat on top & didn't have anywhere for the metering lever to hook.The metering lever just sat on top of the needle.With the new style lever & needle am I supposed to hook it or just set it in like the old style?

There was a difference in some of those levers and needles in later aftermarket kits. If it rests on top of the needle it should be square on the end of the lever. If it should be hooked in the needle like say a walbro it will be formed on the end and the needle will have the groove for it. When changing the needle you must pay close attention to the old one. The older HL had a brass or metal tip on the needle and the seat was rubber. The kits you buy today the tip of the needle will be rubber and will not seal with the rubber in the seat. If you change the needle it is very likely you will need to change the seat

Thanks for your input John.I already knew about the difference in the needle tips & seats.I did change out the seat with the new one that came in the kit.When it comes to these older HL carbs I only use genuine Tillotson kits.I know guys who use the Chinese kits & say they don't have any problems,but I just don't trust them.I'll pull the carb again tomorrow,not a problem on those old C series saws as there's plenty of room in the airbox to work,& I'll go through the carb again.If I can't find anything wrong,then I'll be stumped.

It's a runner! (almost) I pulled the carb off this a.m. & took it apart & found the problem immediately.The welch plug had come out of it's well.I put it back in & made sure it didn't come out again,then reassembled the carb & reinstalled it & within 2-3 pulls it was running,but as usual it's in dire need of crank seals.Since I've never replaced a crank seal & didn't want to mess up a good saw,I'll pull the seals out of the parts saw for practice.
